How would I pass same arguments to Python script within Eclipse(Pydev) ???
我如何将相同的参数传递给 Eclipse(Pydev) 中的 Python 脚本？？？

If you want your program to ask for arguments interactively, then they cease to be commandlinearguments, as such. However you could do it something like this (for debugging only!), which will allow you to interactively enter values that the program will see as command line arguments.
如果您希望您的程序以交互方式请求参数，那么它们就不再是命令行参数。但是，您可以这样做（仅用于调试！），这将允许您以交互方式输入程序将视为命令行参数的值。
import sys
sys.argv = raw_input('Enter command line arguments: ').split()
#Rest of the program here
Note that Andrew's way of doing things is muchbetter. Also, if you are using python 3.*, it should be inputinstead of raw_input,
请注意，安德鲁的做事方式要好得多。另外，如果您使用的是 python 3.*，它应该是input而不是raw_input，

Click on the play button down arrow in the tool bar -> run configurations -> (double click) Python Run -> Arguments tab on the right hand side.
单击工具栏中的播放按钮向下箭头 -> 运行配置 ->（双击）Python 运行 -> 右侧的参数选项卡。
From there you can fill out the Program Arguments text box:
从那里您可以填写 Program Arguments 文本框：

Select "Properties" -->> "Run/Debug Settings".
选择“属性”-->>“运行/调试设置”。
Select the related file in right panel and then click on "Edit" button. It will open properties of selected file. There's an "Arguments" tab.
在右侧面板中选择相关文件，然后单击“编辑”按钮。它将打开所选文件的属性。有一个“参数”选项卡。

What I do is:
我要做的是：
Open the project in debug perspective. In the console, whenever the debugger breaks at breakpoint, you can type python command in the "console" and hit return (or enter). There is no ">>" symbol, so it is hard to discover.
在调试角度打开项目。在控制台中，每当调试器在断点处中断时，您可以在“控制台”中键入 python 命令并按回车（或回车）。没有“>>”符号，所以很难发现。
But I wonder why eclipse doesn't have a python shell :(
但我想知道为什么 eclipse 没有 python shell :(

Years later, and not Eclipse,
but a variant of other answers to run my.py M=11 N=None ...in sh or IPython:
多年后，不是 Eclipse，而是run my.py M=11 N=None ...sh 或 IPython中其他答案的变体：
import sys
# parameters --
M = 10
N = 20
...
# to change these params in sh or ipython, run this.py M=11 N=None ...
for arg in sys.argv[1:]:
exec( arg )
...
myfunc( M, N ... )
